This paper presents a comprehensive mathematical analysis of thrust augmentation in air breathing jet engines through the injection of ammonia into the compressor stage. The concept of employing ammonia injection to enhance compression efficiency and subsequently augment thrust in jet engines has gained significant attention due to its potential to improve performance metrics and reduce environmental impact. The study begins by elucidating the fundamental principles governing the behavior of gas turbine engines and the thermodynamic processes involved in the compression stage. Utilizing established mathematical models of compressor performance and gas dynamics, the impact of ammonia injection on compression ratio and overall engine efficiency is rigorously examined. Key parameters including compressor pressure ratio, temperature rise, and specific fuel consumption are analyzed to quantify the performance benefits achieved through ammonia injection. Furthermore, the paper investigates the optimal injection strategies and ammonia flow rates to maximize thrust augmentation while ensuring engine stability and operational safety. The mathematical formulations are validated through experimental data from relevant literature. The findings demonstrate the feasibility and effectiveness of utilizing ammonia injection as a viable method for thrust augmentation in air breathing jet engines, offering insights into potential advancements in engine design and operational strategies to meet the demands of future aerospace applications
